FIG. 3 is a view similar to FIG. 2 showing the roof area structure inthe stowed configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to the drawings and initially to FIG. 1, there is shown acollapsible canopy structure 1 in an erected configuration. The canopystructure has a supporting framework comprising upright support framelegs 2 and longitudinally extending support frame members 3 covered witha fabric cover having a roof section 4 and side curtains 5 (only the oneside curtain is shown in FIG. 1 for clarity of explanation).

The roof cover 4 forms part of the roof area structure 5 which isprovided with three u-shaped frame members 6,7,8 which are pivotallymounted to a storage section 12 of the structure 1. The leg supports 2are also supported from the storage section 12.

The arrangement is similar in many respects to the arrangement shown inGB2383351. As shown in FIG. 3, the storage section 12 is connected to acorresponding section 13 extending parallel to one-another and spacedapart. An interconnecting frame member 14 is provided at one side of thearrangement. The frame section comprising the elements 12, 13, 14 isfabricated as a unitary item which is arranged to be demountably securedto the roof of a transportation vehicle. Storage section 13 is providedtoward the forward end of the roof of the transportation vehicle.Storage section 12 is provided to the rear end of the roof of thetransportation vehicle and the interconnecting frame member 14 extendsalong the roof of the transportation vehicle between the storagesections 12, 13. The storage sections are provided on their respectiveundersides with means for clamping to roof bars or racks provided on thetransportation vehicle.

The u-shaped frame elements 6,7,8 are stored as shown in FIG. 3 pivotedto lay flat nested one within another within the boundary defined by thestorage sections 12,13, and frame member 14. The support frame legs 2are pivotally mounted by extensions 27 to the respective storagesections 12 and 13 and pivot from the erected supporting configurationshown in the drawings, to be stored extending horizontally between theopposed storage sections 12, 13. The extensions 27 slide into therespective storage sections 12, 13, and lock for transportation in thestowed position. In the supporting position stays 25 hold the supportframe legs 2 in their upright position. The longitudinally extendingframe members 3 are demountable to be stored either internally of thevehicle or underslung below the support section 12, 13, 14 positioned onthe roof of the vehicle.

In a similar manner to the arrangement of GB2383351 the support framelegs 2 are provided on rollers 15 and the support legs 2 are connectedto the respective frame sections 12,13 enabling the whole arrangement tobe lifted clear of the roof of the transportation vehicle.

From the position shown in FIG. 3, the roof area section is erected bypivoting the u-shaped frame members 6, 7, 8 about their pivotableconnection to the respective sections 12, 13 such that they reach theconfiguration shown in FIGS. 2 and 3. By drawing the front frame member6 from the stowed position, the connected canopy causes the adjacentframe members 7 and 8 also to be successively drawn from the stowedposition.

The configuration shown in FIG. 2 corresponds to the arrangement shownin FIG. 1, however, in FIG. 2 the fabric canopy is not shown in thedrawings.

As can be seen clearly from FIG. 1, the distal end 17 of the structureis closed by means of the fabric canopy attached to the frame elements20 and 21. The proximal end 18 of the structure is rendered open andprovides a docking opening enabling the front or rear end of a vehicleto be driven into the canopy arrangement. Because the roof areastructure 5 is pivoted to extend upwardly from the stowed position shownin FIG. 3 to the erected position shown in FIGS. 1 and 2, vehicles ofheight significantly greater than the height of the transportationvehicle can be accommodated for docking with the structure. Inparticular, because the front, middle and rear u-shaped pivotablesupport members 6,7,8 can be positionally adjusted, significantlydifferent height vehicles can be accommodated in the docking area.

It is important to ensure that an effectively isolated environment isprovided in the interior of the canopy to enable adequate repairconditions to exist and also fume extraction apparatus to be operated toeffectively filter any particulates and harmful gases without allowingthese to escape to the exterior of the canopy. Therefore, it isimportant to ensure that the docking end of the canopy within which thevehicle is positioned, is secured along the roof and side walls of thevehicle to a degree sufficient to provide a controlled workingenvironment cut off from ambient external conditions. An absoluteairtight seal is not required but the loose curtains of the canopy needto be held in some way against the side of the vehicle and the magneticsecuring means achieves this well.

This is therefore conveniently achieved by means of the magneticsecuring strips 22 which are used to secure the flexible material of thecanopy to the sides and roof of the vehicle.

The magnetic securing strips may be provided free of the material of thecanopy and simply positioned to sandwich the canopy material between therespective strips 22 and the vehicle. Flexible elongate magnetic stripsare conveniently used.

Alternatively, it is possible that the strips 22 may be providedincorporated with the canopy material (for example, by stitching into ahem or fold of the material).

The invention provides a convenient and quickly erectable structurewhich can be transported conveniently to a location for use and readilyerected into position. The arrangement enables vehicles of significantheight to be partially enclosed and docked in a secure and sealed mannerto enable an adequate environment for vehicle repair to be createdaround the respective end of side of vehicle that needs to be repaired.A working zone is provided about the end or side of the docked vehicle.

The canopy material of the roof area 5 frame members 6, 7, 8 remainsattached to those frame members when the roof area structure is in thestowed or erected position. The remaining frame elements 2, 3, 20, 21are removed from loops or sheaths provided on the canopy material andstowed otherwise. The canopy material is folded and stowed on top of theframe members 6,7,8 laying flat in their stowed position.

There have been described and illustrated herein several embodiments ofa safety harness system and corresponding method of operation. Whileparticular embodiments of the invention have been described, it is notintended that the invention be limited thereto, as it is intended thatthe invention be as broad in scope as the art will allow and that thespecification be read likewise.
